A chromosome-level genome of Lobelia seguinii provides insights into the evolution of Campanulaceae and the lobeline biosynthesis.
Lobelia seguinii is a plant with great ecological and medicinal value and belongs to Campanulaceae. Lobelia contains lobeline, a well-known compound used to treat respiratory diseases. Nevertheless, lobeline biosynthesis needs further exploration. Moreover, whole-genome duplication (WGD) and karyotype evolution within Campanulaceae still need to be better understood. In this study, we obtained a chromosome-level genome of L. seguinii with a size of 1.4 Gb and 38253 protein-coding genes. Analyses revealed two WGDs within Campanulaceae, one at the most recent common ancestor (MRCA) of Campanula and Adenophora, and another at the MRCA of Lobelioideae. Analyses further revealed that the karyotype of Platycodon grandiflorus represents the ancient type within Asterales. We proposed eight enzymes involved in the lobeline biosynthesis pathway of L. seguinii. Molecular cloning and heterologous expression of phenylalanine ammonia-lyase (PAL), a candidate enzyme involved in the first step of lobeline biosynthesis, verified its function to catalyze the deamination of phenylalanine to cinnamic acid. This study sheds light on the evolution of Campanulaceae and lobeline biosynthesis.
期刊介绍：
Genomics is a forum for describing the development of genome-scale technologies and their application to all areas of biological investigation.
As a journal that has evolved with the field that carries its name, Genomics focuses on the development and application of cutting-edge methods, addressing fundamental questions with potential interest to a wide audience. Our aim is to publish the highest quality research and to provide authors with rapid, fair and accurate review and publication of manuscripts falling within our scope.
